The Pattern Makers' League of North America (PMLNA) was a labor union representing patternmakers in the United States and Canada.
The union was founded on May 18, 1887, in Philadelphia, as the Pattern Makers' National League of North America. It was chartered by the American Federation of Labor in 1894, and adopted its long-term name in 1898. By 1925, the union had 8,985 members.[1] [2]
In 1955, the union transferred to the new AFL–CIO, and by 1957, it had 15,000 members.[3] However, membership in 1980 had fallen to only 9,600.[4] On October 1, 1991, it merged into the International Association of Machinists.[5]
